SPECIFICATION forming 'part of Letters Eatent No. 667,637, datedFebruary 5, 1901.

Application filed August 1,1900. Serial No. 25,552. (No model.)

T0 ttl/f 'Lu/tom t may concern:

Be it known that I, AXEL A. STROM, a citizen of the United States,residing at Austin, in the county ot' Cook and State ot Illinois, haveinventedanew and useful Improvement in Railway-Switches, of which thefollowing is a specification.

My object is to provide an improved adjustment for the point-rails ofsplit switches for taking up the wear upon the switchr'ails and otherparts of the switch, so as to enable the switch-rails to be readilyadjusted to the desired degree of iineness for maintaining the properextent of their throw. To this end I adapt the tie-bar, which extendsbetween the switch-rails for connecting them and holding their gage, tobe adjusted at one end or at both ends transversely of the railsin avertical plane for the purpose of spreading the point-rails fartherapart or bringing them closer together, according to the nature of theladjustment required.

The simplest form of mechanism known to me for the embodimentk of myinvention is that illustrated in the accompanying drawings, n which-Figure l is a broken plan view of a railway-switch equipped with myimprovement, and Fig. 2 a section taken at the line 2 on Fig. l andViewed in the direction of the arrow.

A A are the main or stock rails, and B B are the movable point-rails ofa split switch. To the inner sides of the point-rails are bolted clips CC, each havinga depending bifurcated portion C, provided with a verticalrow of holes a at suitably-close intervals apart.

D is the tie-bar for connection at one end with a switch-stand, (notshown,) and which extends toward its opposite ends between the dependingportions of the clips, at each of which it is provided with a hole (notshown) to be brought coincident with opposite holes a in a clip part C,where it is fastened by a pin h or bolt, passed through the coincidingholes in the clip part and tie-bar.

For the original setting of the gage of the switch-rails the relativelocation of the holes in the tie-bar may be such as to require one tocoincide with the lowermost pair of holesl a in a clip part C and therebe fastened by a bolt h, and the other to coincide with an upper pair ofholes ain the opposite clip part C', there to be similarly fastened.Thus in the original setting of the switch-rail gage the tie-bar wouldincline from the horizontal from one end to the other, and to Widen thegage Jfor taking up Wear on the point-rails or other connecting parts ofthe switch construction the tie-bar may be raised at one end to bringthe hole at that end between a higher coincident pair ot` the holes o inthe adjacent depending clip portion, where it would be fastened by abolt b, or it may be lowered at the opposite end to bring the hole atthat end between a lower coincident pair of the holes a in the adjacentdepending clip portion, where it would be thus fastened, or, if desired,one end of the tie-bar may be raised to be supported in ahigher pair ofthe holes a, and the other may be lowered to be supported in a lowerpair of the holes a.

The particular means shown and described are herein presented merely asone of various means for the embodiment of my invention, which consists,broadly, in adapting the connecting medium between the switch-rails toproduce their adjustment by raising or lowering it in a vertical plane.Hence I do not limit my invention to the particular means set forth asembodying it, but intend to be understood as including therein any othermeans, whether involving crank, eccentric, or other suitable mechanismfor effecting the adjustment, provided the means employed serve thepurpose of carryingV out the principle of my invention of producing theswitchrail adjustment by raising or lowering in a vertical plane theconnecting medium j between the switch-rails.

What I claim as new, and desire to secure by Letters Patent, is

l. In a railway-switch, the combination with the switch-rails of aconnecting medium between them, adjustable by raising and lowering it ina vertical plane along a vertical extension from the rail to set thegage.

I n a railway-switch, the combination with the switch-rails of a tie-barconnecting them and adjustable by raising and lowering it in a verticalplane along a Vertical extension from the rail to set the gage.

IOO

3. In a railway-switch, the combination with the switch-rails providedwith pendants, of a tie-bar connecting them and adjustable by raisingand lowering it in a vertical plane to set the gage.

4. In a railway switch, the combination with the switch-rails of clipsfastened thereto and having pendent portions provided with rows ofholes, a tie-bar extending between said clip portions and having holesto coincide with the holes in said clip portions, and pins for fasteningthe tie-bar through said holes, said tie-bar being adjustable by raisingand lowering it in a vertical plane to bring its holes coincident withdifferent holes in said clip portions, substantially as described.
